The aim with this study is to provide immunotherapy with vitamin D and phenylbutyrate to treatment-naive HIV infected patients to induce important antimicrobial defence mechanisms and decreased inflammation.

Plasma HIV viral load will be used to monitor efficacy of vitamin D and phenylbutyrate treatment among treatment-naïve HIV patients at the time of diagnosis (time point 0) and at 4, 8, 16 and 24 weeks after initiation of antimicrobial treatment with vitamin D and phenylbutyrate. The primary endpoint will be assessed at 16 weeks compared to baseline (time point 0).

Patients with medical contra-indication for biopsy such as bleeding tendencies.

Hypercalcaemia (serum calcium > 3,0 mmol/L) identified at baseline.

Pregnant and breast feeding women.

Any known liver or kidney function abnormality, malignancy or patients treated with cardiac glycosides.
